The NRC staff began with a brief overview of the subsequent lic ense renewal (SLR) process.
The process consists of two tracks: the environmental review an d the safety review. During the meeting, the staff shared a tentative review schedule. For an a pplication submission date of April 2024, the final licensing decision is to be determined pe nding the Environmental review.
For the Dresden SLRA, the NRC staff has incorporated process im provements and lessons learned from previous SLRA reviews.
CEG then began its presentation with general plant information of Dresden Units 2 and 3. The initial license renewal application was submitted on January 3, 2003, and approved on October 28, 2004. The Dresden Unit 2 current license expiration date is December 22, 2029, and it entered its initial period of extended operation (PEO) o n December 22, 2009. The Dresden Unit 3 current license expiration date is January 12, 2 031, and it entered the initial PEO on January 12, 2011.
CEG stated that the format and content of the Dresden SLRA is b ased on NUREG-2192, Standard Review Plan for Review of Subsequent License Renewal Applications for Nuclear C. Wilson
Power Plants, Revision 0 (ML17188A158), NUREG-2191, Generic A ging Lessons Learned for Subsequent License Renewal (GALL-SLR) Report, Revision 0, Volu mes 1 and 2 (ML17187A031 and ML17187A204 respectively), Regulatory Guide 1. 188, Standard Format and Content for Applications to R enew Nuclear Power Plant Operating Licenses, Revision 2 (ML20017A265), and SLR Interim Staff Guidance.
CEG presented on its safety application approach, which utilize d Nuclear Energy Institute (NEI) 17-01, Revision 0, and included discussion of the compreh ensive scoping and screening evaluation, aging management review, aging management programs (AMPs), time limited aging analyses, and operating experience. The applicant stated that i ts goal for AMPs is to maximize consistency with the GALL-SLR Report. CEG also noted that its i nitial review period for operating experience spanned 2013 to 2022, that it will perform a gap review prior to submittal, and that no new aging effects had been identified to date.
The application for Dresden Units 2 and 3 is expected to have a total of 47 AMPs. Of the 47 AMPs, 35 are existing while 12 are new and not a part of their initial license renewal. A total of 18 AMPs are expected to be consistent with the GALL-SLR Report; 18 AMPs are expected to be consistent with enhancements; five AMPs are expected to be c onsistent with exceptions; and six AMPs are expected to be consistent with exceptions and enha ncements. Dresden does not plan to have any plant-specific AMPs.
To support its SLRA, CEG stated that it is utilizing lessons le arned from previous CEG and industry license renewal projects. This includes its extensive aging management experience and participation in NEI and Electric Power Research Institute initiatives related to license renewal and long-term operations. CEG noted that it reviews bre akout questions, requests for additional information, requests for confirmation of informatio n, and supplements associated with recent license renewal applications to ensure consistency with current NRC expectations and SRP-SLR guidance. CEG also stated that an industry peer rev iew of the SLRA will be performed. CEG will also utilize the Scientech eDocs portal to support the NRC review.
During the NRC/CEG question and answer portion of the meeting t he NRC staff had several questions. One question was regarding the number of AMPs for bo th the Clinton initial license renewal application and Dresden SLRA; CEG responded with additi onal information for both applications. Another staff asked to provide additional informa tion regarding how operating experience that occurs during the review is addressed by the ap plicant; CEG discussed its approach and processes that it utilizes to disposition and addr ess operating experience at its site, including its evaluation of Regulatory Issue Summary (RIS ) 2014-06, Consideration of Current Operating Issues and Licensing Actions in License Renew al, (ML13177A325). The NRC staff also asked additional information regarding the use a nd timing of the portal during the staff review. The NRC project manager responded, which was conf irmed by CEG, that the specific logistics regarding the portal have yet to be determin ed.
During the public comment portion of the meeting, one member of the public asked to repeat the reference to RIS 2014-06, which was provided by the NRC staff. There were no additional questions from members of the public.
The NRC staff and CEG concluded the meeting by mentioning that they would like to continue early engagements to optimize the most efficient review of the Dresden SLRA.
